Description

Die Erfindung bezieht sich auf eine Abstützvorrichtung für einen Fahrzeug-Achsstabilisator, mit einem in Fahrtrichtung schwenkbaren Verbindungslenker zwischen Fahrgestell und Stabilisator (siche z.B. FR-A-2529838 oder DE-A-2842429).The invention relates to a support device for a vehicle axle stabilizer, with a connecting link which can be pivoted in the direction of travel between the chassis and the stabilizer (see e.g. FR-A-2529838 or DE-A-2842429).

Die meist als U-förmig gebogene Torsionsfedern vorgesehenen Stabilisatoren sollen vor allem den Wankneigungen des Fahrzeuges bei Kurvenfahrt entgegenwirken, wozu sie einerseits an der Fahrzeugachse, anderseits am Fahrgestell angelenkt sind. Da die Fahrzeugachse aufgrund ihrer Federung eine Einfederbewegung ausführt, die nicht nur eine vertikale, sondern auch eine in Fahrtrichtung liegende Komponente aufweist, muß die fahrgestellseitige Abstützung des Stabilisators diese Längsbewegung aufnehmen können, wozu bisher Verbindungslenker in Form von schwenkbaren Laschen eingesetzt werden. Die über ein gummielastisches Lagerelement am Stabilisator angreifenden Laschen erfordern daher auch fahrgestellseitig eine bewegliche Lagerstelle, beispielsweise ein Gummigelenk oder eine Bolzen-Büchsenlagerung, die allerdings nicht nur aufwendig, sondern auch einem starken Verschleiß unterworfen ist und daher auch oft durch auftretende Klappergeräusche, übermäßige Lagerspiele u.dgl. Anlaß zu Beanstandungen und Reparaturen gibt.The stabilizers, which are usually provided as U-shaped torsion springs, are primarily intended to counteract the roll tendencies of the vehicle when cornering, for which purpose they are articulated on the vehicle axle on the one hand and on the chassis on the other. Since the vehicle axle performs a compression movement due to its suspension, which not only has a vertical but also a component lying in the direction of travel, the chassis-side support of the stabilizer must be able to absorb this longitudinal movement, for which purpose connecting links in the form of pivotable brackets have previously been used. The tabs attacking the stabilizer via a rubber-elastic bearing element therefore also require a movable bearing point on the chassis side, for example a rubber joint or a pin-and-bush bearing arrangement, which is not only complex, but also subject to severe wear and tear and therefore often also caused by rattling noises, excessive bearing play and the like . Like. There are grounds for complaints and repairs.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Abstützvorrichtung der eingangs geschilderten Art zu schaffen, die sich sowohl durch ihre Einfachheit als auch durch ihre Funktionstüchtigkeit und Verschleißfestigkeit auszeichnet.The invention is therefore based on the object to remedy these deficiencies and to provide a support device of the type described, which is distinguished both by its simplicity and by its functionality and wear resistance.

Die Erfindung löst diese Aufgabe dadurch, daß der Verbindungslenker als am Fahrgestell eingespannte Biegefeder ausgebildet ist. Für die Stabilisatorabstützung am Fahrgestellt gibt es daher keine bewegliche Lagerstelle mehr, da die Biegefeder starr am Fahrgestell befestigt wird und eine Schwenkbewegung in Fahrtrichtung allein aufgrund ihrer Biegefähigkeit ausübt. Ein einfaches Federblatt, das durch eine entsprechende Dimensionierung den auftretenden Druckbelastungen ohne Knickgefahr standhält und einen auf die mögliche Schwenkbewegung angepaßten zulässigen Biegebereich aufweist, genügt als Verbindungslenker, der aufwandsarm am Fahrgestell zu befestigen ist und seine Stützfunktion für den Stabilisator mit vollem Längsbewegungsausgleich auch bei gelenkslosem Ansatz am Fahrgestell einwandfrei erfüllt.The invention solves this problem in that the connecting link is designed as a spiral spring clamped on the chassis. There is therefore no longer a movable bearing point for stabilizer support on the chassis, since the spiral spring is rigidly attached to the chassis and pivots in the direction of travel solely on account of its flexibility. A simple spring leaf, which withstands the pressure loads occurring without risk of kinking and has a permissible bending range adapted to the possible swiveling movement, is sufficient as a connecting link, which can be attached to the chassis with little effort and its support function for the stabilizer with full longitudinal movement compensation even with a jointless approach fulfilled on the chassis.

Eine besonders zweckmäßige Konstruktion ergibt sich dabei, wenn erfindungsgemäß die aus einem Federstahlband bestehende Biegefeder an ihrem freien Ende zu einer U-förmigen Halterung umgebogen ist, in der ein gummielastischer Lagerkörper für den Stabilisator sitzt, da so die Biegefeder gleichzeitig auch als eine Art Lagergehäuse für das Stabilisatorlager genützt werden kann.A particularly expedient construction is obtained if, according to the invention, the spiral spring consisting of a spring steel strip is bent at its free end to a U-shaped holder in which a rubber-elastic bearing body for the stabilizer is seated, since the spiral spring also serves as a kind of bearing housing for the stabilizer bearing can be used.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel rein schematisch veranschaulicht, und zwar zeigenIn the drawing, the subject matter of the invention is illustrated purely schematically in one exemplary embodiment, specifically showing

Fig. 1 und 2 eine erfindungsgemäße Abstützvorrichtung in Seitenansicht und Draufsicht.1 and 2 a support device according to the invention in Side and top view.

Eine Fahrzeugachse 1 ist am durch einen Rahmenlängsträger angedeuteten Fahrgestell 2 über Blattfedern 3 und Stoßdämpfer 4 aufgehängt, wobei zur Verringerung der Wankneigung bei Kurvenfahrten ein U-Form-Stabilisator 5 vorgesehen ist. Dieser beiderends über gummielastische Lager 6 an der Achse 1 angreifende Stabilisator 5 wird im Bereich seines Mittelteiles an zwei Stellen über Verbindugnslenker 7 am Fahrgestell 2 abgestützt, welche Verbindungslenker 7 als Biegefedern ausgebildet sind und aus einem Federstahlband 8 bestehen. Dieses Federstahlband 8 ist starr am Fahrgestell 2 festgeschraubt und kann durch seine Biegefähigkeit die in Fahrtrichtung auftretenden Längsbewegungen des Stabilisators 5 aufgrund einer Einfederung der Achse 1 aufnehmen und ausgleichen. Da Federstahlband 8 ist an seinem freien Ende zu einer U-förmigen Halterung 9 umgebogen, in der ein gummielastischer Lagerkörper 10 für den Stabilisator 5 sitzt.A vehicle axle 1 is suspended from the chassis 2, indicated by a longitudinal frame member, via leaf springs 3 and shock absorbers 4, a U-shape stabilizer 5 being provided to reduce the tendency to roll when cornering. This stabilizer 5, which acts on the axle 1 at both ends via rubber-elastic bearings 6, is supported in the region of its middle part at two points via connecting links 7 on the chassis 2, which connecting links 7 are designed as spiral springs and consist of a spring steel strip 8. This spring steel strip 8 is rigidly screwed to the chassis 2 and, due to its flexibility, can absorb and compensate for the longitudinal movements of the stabilizer 5 that occur in the direction of travel due to the deflection of the axle 1. Since spring steel strip 8 is bent at its free end to a U-shaped bracket 9, in which a rubber-elastic bearing body 10 for the stabilizer 5 is seated.

Es entsteht eine besonders einfache, rationell herstellbare, funktionstüchtige und langlebige Abstützung des Stabilisators 5.A particularly simple, rationally producible, functional and durable support of the stabilizer 5 is produced.
